The 27-year-old made a surprise exit from the show on Sunday after Will.i.am opted to take Sophie Griffin through to the live rounds, with the pair going head-to-head during a rendition of Katy Perry’s Firework.

Many viewers were left shocked by the decision after J Marie Cooper emerged as an early favourite during the audition rounds, with all four judges turning around following her impressive rendition of Jessie J’s Mamma Knows Best.

Jessie J had been visibly disappointed after J decided to choose Will.i.am as her mentor, but it seems Cooper has gone on to regret her decision following her premature exit from the show.

Both J and Sophie wowed with their vocal gymnastics during their performances, earning praise from all of the vocal coaches.

But while Tom Jones and Danny O’Donoghue claimed they would take J through to the live finals, Jessie J saved her praise for 17-year-old Sophie, saying her vocals were impressive for such an age.

Will.i.am went on to cite age as one of the main reasons for his decision, explaining that at 17 he had formed the Black Eyed Peas before sending J Marie Cooper home.

Today J used her Twitter account to launch a scathing attack on the programme, saying the programme was called ‘The Voice’ not ‘The Age’.She wrote: ‘Hey peeps, there was a lot cut from my final edit of The Voice, including any emotion or story I might have had… As much as I’m ok with it I don’t feel I was portrayed entirely correctly…I have experience as a singer yes, but needed this opportunity too. I am still working for £7.50 an hour. So the whole “she’s so experienced” thing is a bit much. I am but don’t think that should be a reason not to go through.’I have a lot of love for all of the contestants on The Voice, and I still support the show. But I’m real and always gonna tell it like it is. The fact that I am 27 should not have even been a factor. It’s called “The Voice” not “The Age”. I’m stating facts here.’Have also said all of this to @iamwill. I am a very honest, real person. Always gonna say it as it is.’Cooper went on to insist she had ‘no regrets’ about appearing on the show and claimed she had ‘learnt a lot’ from the experience, adding: ‘I am ok with not going through. Just think the reasons should have been to do with the vocal. The Voice.’

But after her comments were met with a barrage of criticism J felt the need to clarify further, insisting she wasn’t ungrateful while reiterating her bitterness at the decision.’Like to add I AM grateful for the opportunity … 100%. It’s given me a platform I otherwise wouldn’t have had, but to use someone’s age when they are only 27, is not right. You wouldn’t use someone’s race so why use their age. Just saying.’Still grateful to @BBCTheVoiceUK . It’s a great show. I understand the decision just would have liked it to be about The Voice.’She later insisted didn’t bear a grudge against battle rival Sophie and defended her comments, claiming she had ‘made her point’.’Guys… Has nothing to do with how I feel about Sophie. She’s a great singer. Just think the comments should have not been about age!’You know what. I’m human. I have feelings. I’m sensitive. I support the show, have made my point. Have a great day everyone.’VIDEO:Watch Sophie Griffin and J Marie Cooper’s vocal battle
